Tongue & Groove Moulding 3/8" - 4

This tongue & groove paneling 3/8" - 4 measures .375" thickness, the width can be machined to any desired size within the parameters of the moulder or shaper used to mill the pattern. The v shaped profile is composed of a 5/32" wide by 1/4" deep tongue and groove with a 1/8" wide by 1/16" deep chamfer on one edge, there is .012" of void in the joint area for expansion and contraction of the wood during seasonal changes in relative humidity. When two pieces of milled lumber are joined together they create a 1/4" wide by 1/16" deep v groove on the face side of the merged boards.

Our high precision acrylic templates and knives include the required draft angles to maintain the ability to sharpen the blades properly without modifying the detail, while simultaneously prolonging the milling time between sharpening. Whether you own a Weinig, Wadkin, Leadermac, SCM, Diehl and Kentwood moulder, our cutters will mill flawlessly on them all. From just an idea in one's mind, to reality in their home, our custom profiles reflect the creative style of your imagination, let us assist you in complementing the architectural decor of your home with any of our attractive molding patterns.

Grade of Steel

V2+RW

V2+RW Rockwell Hardness about 58-62, Good Quality. Made for short runs, (1' - 1000') of high quality millwork. This steel is flash coated with a special hard chrome coating (.001") thick to help provide very long wear on the cutting edge. It will outlast any standard M-2 steel that's not coated. This steel is easy to grind with standard grinding wheels and borazon finish wheels. This steel is easy to joint on high speed machines.

BLACK NITRIDE Rockwell Hardness about 70-72 (Surface Only), Premium Quality. Black Nitride (carbon nitride) steel offers longer run times than standard M2 or M3 high speed steel (1' - 2000'). Adding pure carbon to the top surface of the knife steel hardens the cutting edge about .010" to obtain about a 72 Rockwell. Steel is black oxide to reduce pitch build up and rust, this also gives the steel a uniform color due to the case hardening. Because the steel is case hardened and higher on the Rockwell scale this steel is more brittle than other non-case hardened steels. Excellent for stubborn hardwoods and softwoods, but not recommended for knotty woods or very large cuts over 1" depth of cut.

ENDURANCE Rockwell Hardness about 70-72 (Surface Only), Superior Quality. Endurance super run is the premium of all high speed knife steels. They start with V2 base, then apply P.V.D. (Physical Vapor Deposits) in an Ion sputtering magnetron chamber. These deposits consist of a five layer film of Aluminum, Chromium, Molybdenum, Nitride, and Titanium. This forms an extremely hard and heat resistant cutting edge twice as hard as C2 grade carbide. Because the coating is so thin, normal vitrified rough wheels and CBN finish wheels can be used on this product. Special care must be taken not to hone the face of the tool with anything but a block of wood. Tool life is increased up to 600 percent over normal high speed steel. Small amounts of MDF (500' or Less) can be run with this product.
